To (1. whom, it may concern:

' Be it known that we, FRANK D. GREEN and JOHN P. MACLEARN, citizens of the United States, and residents of Philadelphia, Pennsylvania, have invented certain Improvements in Apparatus for Charging Liquids with Carbonic-Acid Gas, of which the following is a specification.

Our invention relates to apparatus for impregnating a liquid, usually water, with carbonic acid gas.

One object of our invention is to insure a rapid and thorough .commingling of the gas andliquid during the feeding of the gas, and

'a further object of our invention is to provide an apparatus, duplex in form, that is adapted to work continuously, that is to say, one portion of the same will always be carbonating or storing liquid, while a corres onding portion of the apparatus is dise arging liquid which has been carbonated. Other features, as well as the details of our invention will be pointed out hereinafter, reference being had to the accompanying drawings, in which:

Figure 1, is an elevation, partly in section, of the improved apparatus forming the subject of our invention; Fig. 2, is a sectional view illustrating a detail of our' invention,

and Figs. 3 to 5, inclusive, are diagram views illustrating a detail of our invention.

its operating mechanism.

In the improved apparatus which we have devised, we have dispensed with the use of an auxiliary pump to, effect the entrance of the liquid to' be carbonated. In apparatus where pumps are employed, great difhculty exists when recharging the same, for the reason that the pressure in the tank frequently overcomes the pressure exerted by the pump, resulting in the straining of the latter or Moreover, when umps are used, the valves and packings are iable to leak, or permit the gas to back up the water supply with consequent loss of gas.

A further reason for dispensing with the use of a pump is because such device throws a very small stream, entailing considerable labor when the work. is done by hand, and considerable loss of time when such work is done by the aid of power. In our apparatus, weprefer to blow off all the vapor of gas and air remaining from eachprevious charge, and We have found that this operation is very inexpensive,.for the reason that the vapor so shown at 15 and 15.

discharged is of little commercial value, as it is down to a very low pressure after the liquid contents of the tank have been drawn off,

- and also because it is largely an admixture of air which has been displaced from the liquid by the gas on the entrance of the latter into the carbonating tank.

In the accompanying drawings, 1 and? represent tanks of suitable dimensions, which are preferably supported by a common base 2. In these tanks the liquid to be charged 18 stored. At the to of each tank is a multiple valve casing 3 an 3 having three outlets or passages, two of which are controlled by the valves 4 and 4, and 5 and 5. The outlets 6 and 6 for the passage of water are not controlled by valves, as the water pipes 7 and 7' are provided with suitable cut-off or check each of the multiple valve casings 3 and 3 are the pipes 9 and 9, and 10 and 10; the pipes 9 and 9 serving to convey into the tank the gas from any suitable source of supply, while the pipes 10 and 10. serve to carry off and discharge into a suitable pipe 11 the carbonated or charged liquid. Each. of the through openings for the pipes 9 and 9, and 10 and 10 is provided with valves 4 and fl, and 5 and 5, as before noted whereby inlet and outlet may be cutoff at the casings 3 and 3, but in practice these valves aresnormally open, as the passage of the gas andhquid respectively through said pipes 9 and 10 1s eon trolled by other valves shortlyqto be de-.

inders 14 and 14, each of which communicates with the interior of the tanks 1 and 1*,

preferably by means 'ofthe rubber tubing The I \Iipper portion of each tank is connected' by cans of chains 16 and 16 to weighted levers 17 and 17'f piv-- oted at 18 and 18 to the top of the tanks 1 and 1, oneof-which levers, when either of the tanks 14 or 14 is light, tends to raisethe same and when said tank is in a raised position and the lever is in a lowered position, the

latter is arranged to open an air vent valve 19 or 19 arranged in the upper portion of the tank. To each tank 14 and 14 rods 20 and 20 are secured, which rods serve to operate a series of valves controlling the passage of gas to the tanks and the passage of the carbonated liquid away from such tanks.

In the drawings, the T-section carries a two-armed lever 26 with pivotal connections at 27 and 27 to the weighted levers 28 and 28 controlling the gas valves? 29 and 29 Each lever 28 and 28 is provided with a weight 30 and 30 f0r a purpose shortly to be described.

The T-secti0n carries the two-armed lever 36, to each end of which at 37 and 37 a are pivoted the levers 38 and 38 controlling the valves 39 and 39 which directly control the 14 and 14 alternately rise and fall, theywill alternately open and close the several valves 29 and 29 and 39 and 39, the gas being alternately directed to the tanks 1 and 1 and the carbonated liquid discharged alternately from said tanks.

Carried by each of the levers 28 and 28", are spring controlled pawls 41 and 41 adapted to engage notches 42 and'42 formed in the rods 20 and 20, the result of such connections being that, when either of said rods 1s moved downward, such movement will 0 en one of the gas valves 29 and 29 and c ose the other, the one opened being the one whose lever has its spring pawl 41 or 41 in engagement with the notch of the rods 20 and 20*. The valve that is opened by the downward movement of the rod, is opened gradually, until its weight passes the center while the valve that is closed by such action is closed rapidly by reason of the weight. 30 or 30 falling over as soon as the lever passes the center; the rapid movement taking place in the final opening and closing of the respect1ve valves. The rods' on age the s ring pawls of the valve levers on y on the ownward movement, such rods sliding freely past said awls when raised. -It is uite essential t at'the gas valves'b e close ra'idl order to promptly shut off the supp y 0 gas and prevent any loss of the same.

The tanks may have means for assisting the admixture of gas and liquid, sirchas the perforated disk 45, and the gas pipe entering It will thus be seen, therefore, that as the tanks each of said tanks is carried beneath said disk so that the gas entering the tank passes under this plate and passing upward through the perforations of said plate, slowly bubbles through the liquid in the tank. If desired the water may be introduced at the top of the tank in the form of spray, falling down through the atmosphere of gas remaining from the previous charge.

In the drawings, the tank 1 is supposed to be empty, while the tank 1 is filled and discharging its carbonated liquid. In practice, with the parts in position. as shown in the drawings and as soon as the balance tank 14 has received, through one of the hose connections, su'llicient liquid to overcome the weighted lever 17, said balance tank will fall, and in falling, carries with it the rod 20. As this red only acts upon the levers controlling the valves of the carbonated liquid pipes when rising, said valves will be undisturbed.

The rigid connection, however, withthe levers controlling the gas valves is such that as soon as said balance tank falls, thegas valve 29 will be opened and the valve 29 shut, the closing of the latter being effected in a rapid manner, as described hereinbefore, and the valves will be in the position shown in Fig; 3. The gas will now flow into the tank 1 until it fills the space unoccupied by the liquid, and as it is introduced into said tank in such a way as to thoroughly impregnate such liquid,

the latter becomes thoroughly charged and is readyfor use. The entrance of the gas into the tanks also serves the purpose of cutting off the flow of liquid to the same, by closing the check valves 8 or 8. controlling the flow.

In the meanwhile, the tank 1 has been discharging its carbonated liquid, until the balance tank-becoming light and the weighted lever 17 overcoming the weight of the same, said tank rises and carries up the rod 20 which shifts the lever 36 carried by' the T-section 35 and changes theposition of the valves 39 and 39 controlling the passage 'of'the carbonated liquid, as illustrated in Fig. 4. Thegas valve havingv been shifted as previously noted, so that, in its changed position, both of the valves 29 and 39 are closed, the lowered position of the weighted lever 17 opens the vent valve, ermitting the escape of the vapor in the tan 1* remaining from thepre vious charge, so that liquid flows readily into said tank. As has been noted with reference to the tank 1, the liquid also enters the bal-' ance tank 14, and as soon as a su'llicient uantity has entered said tank to.overcome the resistance of said wei hted lever, the tank 14" drops. As noted Wit regard to the tank 14, this action carries down the rod '20 which does not disturb the valve 39", but leaves it in its closedposition, while the valve 29 opens and the valve 29 closes, with the result that the. gas will flow into the tank 1 and charge the liquid which has previously run into the dent that various modifications may be adopted toperform the same result.

We have shown our apparatus as equipped with liquid gages or glasses 46,.and pressure gages 47 mounted on top of the tanks.
